To aZZ whom it may concern.

Be it known that l, Jason il. Gurnairnnn, a citizen of the United States, and a resident of Chicago, in the county of @ook and State of illinois, have invented certain new and useful improvements in Elevator Legs, of which the following is a full, clear, and exact description. Y

The invention relates to elevator legs. lt is ncrv common practice vto secure sections of elevator legs together, so they Will be of' the desired length, by securing angle irons to the sections respectively and securing the angle irons together. @ne object of the invention is to provide an improved elevator leg in which the sections are joined together Without the use of angle irons.

Another object of the invention is to provide an improved elevator leg in which the sections are secured together by strips of sheet metal which are adapted to lap the abutting flanges on the sections.

The invention consists in the several novel features hereinafter set forth and more particularly dened by claims at the conclusion hereof.

ln the drawings; Fig. l is a vertical longitudinal section of anelevator leg embodying the invention. `Fig. 2 is a section talren on line 2-2 of Fig. l. lig. 3 is a perspective of the several parts of the improved joint disassembled for the purpose of illustration.

The invention is illustrated as applied to an elevator leg adapted to enclose a conveyor belt 18 to which are attached buckets 19. ln practice, these legs are so long that sectional construction is necessary. For this purpose, the leg is formed of a series oi sections having their contiguous ends secured to one another.

Each leg-sectionis formed of a sheet of metal bent to forni three sides il, 5 and b and the fourth side 7 is formed by a separate sheet of metal which has its margins bent to form inner and outer flanges 8 and 9 for lapping the margins and edges of the sides 4; and 6. The strips forming the sides usually extend continuously throughout the length of a section of the leg. Both ends of each side are provided With an outwardly extending flange, the sides e, 5 and 6 being each provided with a flange l0 and the sides 7 with a flange ll. The end flanges Serial No. @4,055

of contiguous sections are adapted to abut and are provided with registering holes 12. A strip i3, which is i-shaped in cross-section, is adapted to lap the flanges il of contiguous sections and a similar three-sided strip ifi is adapted to entend around and lap the flanges l0 on the ends of the sides fil, 5, and 6. Strips i3 and le are provided with holes l5 adapted to register With the holes l2 in the end flanges, and bolts 16 are adapted to pass through the ti-shaped strips and the end flanges to secure the sections together.

rllhe strips 13 and lli are formed of sheet metal and when they are bolted to endiianges of contiguous sections forni a strong joint which will be substantially dust-tight. The strips serve to reinforce the joint so that the connection Will be extremely rigid Without the use of angle iron bands.

The invention is not to be understood as restricted to the details set forth, since these may be modified Within the scope of the appended claims, Without departing from the spirit and scope of the invention.

Having thus described the invention,

What l claim as new and desire to secure byk Letters Patent, is:

l. in elevator leg formed of sheet metal sections, each section comprising a member bent to forni three integral sides, a fourth side being formed of a separate strip and having longitudinal integral flanges lapping the inner and outer faces of the margins of the oppositely disposed sides on said rneniber and extending in the planes thereof, means enten-:ling through the flanges and end margins to secure the sides together, end flanges on and integral with the threesided ineinber and strip respectively, and means to secure the end flanges of contiguous sections togetlier.l

2. An elevator leg formed of sheet metal sections, each section comprising a member bent to forinthree integral sides, a fourth side being formed of a separate longitudinal strip, means to secure said fourth side to the oppositely disposed sides of the threesided member, integral outturned end flanges on the three-sided member and strip, connecting strips having flanges adapted to lap the end flanges of contiguous sections, one of the connecting strips having three sides to lap the Hanges on the three-sided tid wil

member respectively, end means for seeur ing the connecting strips to the end flanges of contiguous sections.

3. An elevator leg formed of sections,- eaoh section having e plurality of sides, one of the sides being formed of n separate strip und having longitudinal flanges lepping the inner and outer faces of the man gins and lche edges of e. plurality of other sides, means extending Jhrough the flanges and said margins to secure the sides together, integral outturned lend flanges on the sides, strips having flanges adapted to lap the end flanges of contiguous sections, and ineens extending through vthe strip flanges and the end flanges to secure the ends of' the sections together.
